The retina, nerve layer in the eye which senses the vision, is normally attached to the inner wall of the eye. The vitreous body fills the posterior cavity of the eye, has a gel-like form and poor attachment with the retinal layer. Due to aging and some diseases, there may be impairments in the vitreous body and it begins to detach from the retinal layer. Patients may experience “ streaks of light “ during separation. This is called vitreous detachment. Sometimes a retinal tear may develop during detachment.
